The formation of the iron(III) thiocyanate complex ion is an exothermic equilibrium system. For each change to the system, indicate how the concentration of each species in the chemical equation will change to reestablish equilibrium. An up arrow indicates an increase in concentration, a down arrow indicates a decrease in concentration, and leaving it blank means there is no change in the concentration.
increasing the concentration of Fe3+
decreasing the concentration of Fe(SCN)2+
increasing the temperature of the system
Think of an experiment you could perform to determine if the iron(III) thiocyanate formation equilibrium is exothermic or endothermic.
